            Bug ID: 208903
           Summary: [SVG] RenderSVGResourceContainer's style invalidation
                    should be a pre-layout task
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org

RenderSVGRoot::layout() -> m_resourcesNeedingToInvalidateClients -> resource->removeAllClientsFromCache() -> RenderSVGResourceContainer::markAllClientsForInvalidation -> RenderSVGResourceContainer::markAllClientLayersForInvalidation -> invalidateStyleAndLayerComposition -> dirty style -> schedule style recalc.

This leads to unstable layout.
